Abstract: With the in-depth application of big data and artificial intelligence in various fields, the standardization of knowledge representation has been mentioned as an important agenda. In order to realize the standardization of knowledge representation, this paper introduces the concept of "Three Worlds" model, that is, the real world, the conceptual world and the computer world. According to this model, things in real world can be abstracted concept in concept system model in concept world. Finally, acoording to concrete standards, the concept system model can be tanslated into information model in computer world, so as to realize knowledge representation. In order to standardize the representation of conceptual system model, series standards of ISO/IEC 11179 MDR is studied, the concept system registration meta-model specification is analyzed, and a seven tuple model of MDR concept system is constructed. In addition, the representation method of the relationship between concepts is defined, which lays the foundation for the representation of conceptual system model. In order to transform the concept system model registered in MDR into OWL ontology representation model in the computer world, the rules of mapping MDR concept system to OWL ontology is defined in the paper. Finally, the concept system registration prototype system was designed and developed to verify the feasibility of the MDR concept system and ontology representation. The research results provide a methodology for the standardization of domain knowledge representation.

Key words: knowledge representation, concept system, concept metamodel of MDR, ontology, standardization
